All,
Thanks for the replies so far. I have to agree with Keith here.
I've been around in tech since the Apple II+ days (before IBM PC)
and have been dismayed at the needless complexity of many systems,
especially on the database side of things. Not that I can complain
too loudly, I made very good money in the later years being hired
on to improve DB efficiency, which almost always was simply
uncomplicating things. @mb - I appreciate your answer and will
look into the technologies you mentioned. But, I was hoping to
have something as simple as what Intel RST does it on the Windows
side. Literally, a set it and forget it proposition. It just
works. And I've had several drive failures over the years and the
recovery was painless and lossless.
So, I'll keep looking...

1984 or so there was a poster in the Army National Guard building
in Tucson that read something like "Keep It Simple Stupid" and
went on to say everything should be at an 8th grade level.
I was first introduced to Linux in 1998... I took my first
programming course in 1983 at the UofA. I was already out of high
school for 8 years.
I've seen a lot of stuff. I've watched things become increasingly
Complicated. I've mentioned this before. Most will shine me on.
I'm currently a PHP developer. Over the years I have had my hands
in a lot of related technologies.
What you describe Michael Butash sounds very complicated. Most
things today seem to be.
Don't get me wrong, I think some advancements are good such as
Proxmox which I use.
How do we uncomplicated all of this stuff.

That sounds like what they call "fakeraid"
using the rst controller,
really there is no need to anymore. For probably 15 years now
i've
used two disks in a linux mdraid volume for boot/rest in raid 1
for
redundancy, usually a crypt volume with luks atop the rest
physical
volume, and lvm atop that, with ext4/xfs atop that. Still do
this
with nvme disks just fine for a few generations of boxes.
I did setup my old desktop as a proxmox box with zfs doing my
raid1
recently booting entirely off that (super dope, +++ for that),
ymmv
per distribution, but that's an option as well for handling all
the
software raid function as well. Ubuntu server with the deb
installer
always handled setting up raid/crypt/lvm/fs just fine, haven't
in a
while personally, but probably still does adequately. I diy
normally
with Arch, but it's what drives this laptop I'm typing on
currently
with a pair of 980pro nvme samsungs doing above.

Hi All,
Ok, I'm finally very close to being able to go to a full Linux
environment and leave the Microsoft ecosystem. I'm
semi-retired and
still do some Microsoft Data Platform work (which was my
career). I
recently got a Dell Latitude and put Kubtunu 22.04 on it and
managed
to get all my applications, dev tools (many MS tools too!),
and
hardware working. I've been down this road before in years
past and
Linux on the desktop was always a "no-go" for me. So, I was
*astonished* how easy it was to install Kubuntu and everything
just
worked. That's how it must feel to be a Mac person! :)
However, one of the hurdles with the Dell was that, by
default, Dell
configures the BIOS such that the boot drive (NVME in this
case) is
set to be in RAID mode instead of AHCI mode, even though there
is
only one drive in the system. This caused Ubuntu to simply not
boot.
After doing some research I came to find the Ubuntu doesn't
support
Intel Rapid Storage Technology (RST), which RAID requires. It
was a
simple fix to reconfigure the BIOS into AHCI mode, since I was
going
to wipe the Windows partition anyway.
But, my main production dev box is Win 10 and I have two NVME
drives
in a RAID 0 (mirror) configuration (using hardware RAID in the
BIOS). If I want to install Ubuntu I need to be able to
implement
this same level of RAID. If Ubuntu doesn't support the Intel
RST
hardware, how can I install Ubuntu and have a RAID 0
arrangement?
I'm not looking for a particular answer to the problem just
some
suggestions on what to research. LVM? ZFS? Software RAID?
Any thoughts would be appreciated.
Peter
